TECHNICAL FIELD

This invention relates to a type of a stoppered discharge system which is designed for toilet reservoir and performs its function with various water volumes.

BACKGROUND ART

Stoppered discharge systems have been used in reservoirs for a long time. There is a need to decrease the amount of water consumed in toilets due to reduced water sources and the methods for fulfilling this need include for example discharge systems with reservoirs of 3-6 liters, toilets which function with less than 6 liters of water or stoppered discharge systems. Therefore user is able to stop the system by intervening water flow after required amount of water is run or enough cleaning is done.

Discharge systems located in reservoir are used in different types for each reservoir trade mark and model. In prior art, in European patent No: EP0892117 an example of stoppered discharge system is illustrated. In this patent, to perform full discharge or discharge in desired amount, elements with magnetic character are used on floating part attached to overflow tube and on the surface in which this part is seated. System of European patent No: EP0892117 which emphasizes on sealing character comprises complex and expensive parts in terms of manufacturing. In European patent No: EP1270831 a reservoir system with double discharge valve is disclosed. In operation, main valve remains opened by the aid of water pressure inside reservoir and second valve controls the amount of water to be added to reservoir by means of at least one floating part. Full discharge and partial discharge could be provided with main valve. The object of European patent No: EP1270831 is to perform operation with less closing noise and with less required force.

In broadly speaking, advantages of stoppered discharge system of the invention used in reservoir are a special formed discharge bearing with double O-ring, a lantern having fingers hereon which could be attached to discharge bearing and a discharge bearing support. In virtue of these structural features, utilization, mounting and maintenance ease could be provided with stoppered discharge placed in reservoir due to its structure and this could be used as a discharge with long-life.

OBJECT OF THE INVENTION

The object of this invention is to achieve a stoppered discharge system which is easily mounted on toilet reservoirs, robust, able to operate with various water volumes and such that a user could discharge any amount of water he/she desired.

Stoppered discharge system (A) of the invention shown in FIGS. 1-4 comprises mechanical parts shown as a discharge bearing (1), a sealing gasket (2), a lantern (3), a discharge tube (4), a pull arm (5), a discharge bearing support (8), a styrofoam clip (9), a styrofoam (10), a segment (11), a discharge gasket (12), a styrofoam lower plate (13), a pull arm connection part (16).

Discharge bearing (1) shown in FIG. 5 comprises a support channel (31) in a track or channel form in which discharge bearing support (8) engages and a finger engagement space (32) on this channel in which discharge bearing support finger (81) (shown in FIG. 9) is attached. Front flat region (37) extends in directly opposite of support channel (31). Front flat region (37) and support channel (31) prevent discharge bearing (1) from rotating in an uncontrolled way by abutting front and back interior surfaces of reservoir. Sealing gaskets (2) are attached into two gasket channels (33) located at cylindrical region (38) on discharge bearing. Discharge bearing (1) is placed into exit channel of reservoir from cylindrical region (38) and is also placed in lower interior surface of reservoir due to rabbetted structure of sitting surface (39) in discharge bearing (1). In stoppered discharge system (A), during discharge, water in reservoir is used by passing from water passage channel (35) into discharge channel (34). The position of lantern (3) is fixed by engaging lantern fingers (41) of lantern (3) shown in FIG. 6 into bearing locks (36) at both sides of discharge bearing (1). The task of two sealing gaskets (2) is to prevent any leaking from discharge bearing (1) in reservoir even if all support or fixing parts of stoppered discharge system (A) are removed. In any deformation or structural change which could be formed in any of sealing gaskets (2) in time, second gasket is provided to keep its sealing function as a safety gasket. Also, styrofoam lower plate (13) is located on styrofoam lower plate sitting surface (30) as shown in FIG. 2 and FIG. 4.

Lantern (3) shown in FIG. 6 has a bottom with an opening and a body having a hollow cylindrical form wherein two wall abutments (42) extending as opposed and in form of an outward protrusion are located near to upper side hereof, a lantern lower rabbet (45) formed by diameter enlargement extends at lower side hereof and two lantern fingers (41) extending as opposed and as an outward protrusion is located on a lantern lower rabbet (45) and a lantern upper opening (43), through which discharge tube (4) is passed, extends at upper side hereof. Lantern upper opening channels (44) facing as opposed, in which discharge tube corrugations (72) of discharge tube (4) shown in FIG. 7 are engaged, extend on interior surface of lantern upper opening (43).

Two wall abutments (42) on lantern (3) serve as a support by tightly abutting front and back interior walls of reservoir to prevent collapse or volume constrictions that might be occurred during plastering and tiling especially in built-in reservoirs and outside effects which obstruct or limit the function of stoppered discharge system (A).

Discharge tube (4) shown in FIG. 7 has also a hollow cylindrical form wherein its upper and lower surfaces are opened, two finger engagement recesses (71) are located on upper side hereof to attach pull arm finger (93) (shown in FIG. 10), segment-gasket sitting surface (75) formed by diameter attenuation at lower side hereof is located where two segments (11) and discharge gasket (12) in between are placed top of each other. Two longitudinal discharge tube corrugations (72) extending as opposed which fit in lantern upper opening channels (44) are located in discharge tube middle portion (77). Two longitudinal discharge tube styrofoam corrugations (76) extending as opposed on styrofoam engagement surface (74) formed by diameter attenuation relative to discharge tube middle portion (77) are located between segment-gasket sitting surface (75) and discharge tube middle portion (77). The rabbet at which discharge tube middle portion (77) finishes and styrofoam engagement surface (74) starts, is styrofoam clip abutment rabbet (73) where styrofoam clip (9) shown in FIG. 11 is fitted. The job of discharge gasket (12) attached on discharge tube (4) is to prevent water leaking from reservoir into toilet by fitting in rabbetted region at the interior surface of discharge bearing (1) (shown in FIG. 2 and FIG. 4) when discharge process is not performed. Segments (11) attached to upper and lower sides of discharge gasket (12) are used to fix the place of discharge gasket (12) on discharge tube (4).

Styrofoam (10) shown in FIG. 8 has a cylindrical structure wherein discharge tube engagement opening (61) is located throughout in the middle, and two longitudinal styrofoam channels (62) extending as opposed, in which discharge tube styrofoam corrugations (76) engage, are located at the interior surface of said opening.

Discharge bearing support (8) shown in FIG. 9 has a body in flat elongated plate form and discharge bearing support finger (81) is located at its one end. This body has a discharge bearing support lower region (83) formed in one-piece to the middle extent hereof and subsequently and a discharge bearing support upper region (85) formed in two arms which has a discharge bearing support space (84) as a long gap in the middle hereof. Discharge bearing support arm (82) located at the other end of discharge bearing support (8) is conjoined with discharge bearing support upper region (85). In mounting of stoppered discharge system (A), discharge bearing support (8) is attached to discharge bearing support channel (31) by discharge bearing support finger (81) and to discharge bearing support finger engagement space (32). In mounted state of stoppered discharge system (A), discharge bearing support arm (82) is attached to a fixed point in the system or in reservoir.

Pull arm (5) shown in FIG. 10 comprises a pull arm grip (94) in a stick form, a pull arm eyelet (91) at one end of this grip in a circular form and pull arm jaws (92) in a U-shaped form at the other end hereof. Also, two pull arm fingers (93) facing as opposed to each other are located at the ends of pull arm jaws (92) and at the interior side of U-form and these fingers are attached into two finger engagement recesses (71) at upper side of discharge tube (4).

Styrofoam clip (9) shown in FIG. 11 is a part attached to styrofoam clip abutment rabbet (73) on discharge tube (4) and is in two nested rings form in which interior ring has an interrupted and elastic structure.

Styrofoam lower plate (13) shown in FIG. 12 has a disk shaped structure and styrofoam lower plate water passage openings (51) are located hereon and in the middle hereof is located a styrofoam lower plate opening (52) having two channels in which styrofoam engagement surface (74) placed on discharge tube (4) could be passed. Styrofoam lower plate (13) shown in FIG. 2 and FIG. 4, in mounted state of stoppered discharge system (A), is located on styrofoam lower plate sitting surface (30) over discharge bearing (1) and on the portion of lantern lower rabbet (45) facing the interior portion of lantern (3). The aim of use for styrofoam lower plate (13) is to provide a sitting surface (1) for styrofoam and to provide discharging of water inside the lantern (3) in a controlled way through styrofoam lower plate water passage openings (51) hereon. Amount of water which lifts styrofoam (10) in the lantern (3) and controls discharge time is adjusted by styrofoam plate water passage openings (51).

In stoppered discharge system shown in FIGS. 1-4, by means of pull arm connection part (16), styrofoam (10) and discharge gasket (12), located in the lantern (3) and fixed to discharge tube (4), are also lifted when pull arm (5) and connected discharge tube are lifted upward. During discharge, as soon as discharge gasket is lifted up, water in the reservoir starts to discharge by passing from water passage channel (35) into discharge channel (34). Discharge tube (4), upon suspending in water, helps discharging of water in the reservoir by means of styrofoam (10). During discharge process, if the user does not intervene, water level drops inside lantern (3) or reservoir and then water could not lift styrofoam (10) therefore discharging process is ended after discharge channel (34) is closed by discharge gasket (12) on the discharge tube (4). However when the user pushes down the pull arm (5) and then connected discharge tube (4) by means of pull arm connection part (16), water flow could be stopped before water level drops upon closing the discharge channel (34) by discharge gasket (12).
